Does email to text via vtext or is there an alternative?

Do either of these supported anymore because I can't get it to work.

There are two ways to text an email to Xfinity phones besides plain old phone number texting.​  ​ ​  ​using: "[phone number]@​​vtext.com​​" works for straight text ONLY.  Also, a character limit is in place.​  ​ ​  ​using: "[phone number]@​​mypixmessages.com​​" works for text, photos, etc.  Characters are not limited to 140.​
